Why is the normal sound card drivers, speaker does not ring?
Trouble phenomenon: the office of a brand computer, a new installation of Win2000. Add the accompanying CD-ROM drive automatically installed the motherboard drivers, integrated graphics card, network card, sound card driver. Reboot the system, the speaker “silence” in the task bar there is the sound card is installed after the success of the small speaker icon. (Please check the sound here is the power plug, and all sorts of excuses interpolation whether this is correct)
Analysis solution: this computer is configured to: 845GL motherboard, Celeron 2.0GHz, 256MB memory, integrated graphics, network card, sound card. Install the system with the driver all the best. Because the task bar on the corresponding icon, so that the speaker problem. Another for a pair of normal speakers, are still silent. Is not the main board behind the sound output jack so bad? As soon as possible will be the speaker input into the front panel headphone hole, as no voice. Is the volume closed? No yes.
I only have to enter the System “Control Panel → System → Device Manager” to view the properties of sound card. The AC’97 onboard sound card is a Realtek AC’97 Audio, from a driver point of view it seems there is no problem
So I would like to Device Manager to remove the sound card after the first reinstall. Did not expect that right-click “Realtek AC’97 Audio”, choose “Uninstall”, then restart the computer suddenly black screen. Intuition told me that the sound card driver problem, how to install it to uninstall the normal error. After restarting the machine, the task bar on the first play a sound card program enhancements closed. Device Manager in the mid-point “Realtek AC’97 Audio” Right-click, choose “Properties → Driver → Update Driver → upgrade device driver wizard → specify the location of choice on CD-ROM Audio directory” a look, there are two directories: One is the (Alcxxx), one (Cmi97xx), this election (Cmi97xx) installation directory, and then everything goes well, restart, fault still. A careful look at the task bar, how the sound card driver or the Realtek AC 97 Audio. Then a setup screen seems to be a bit special
In the “installation of one driver,” the former打钩, point the next step, then the interface appears in Figure 3, the original can have more choices. I chose the “C-Media AC’97 Audio Device”, installed after the restart the computer-driven, and is familiar with the music rang.
Motherboard sound card using the CMI, the need for CD-ROM drive of the C-Media. But at the same time there are Realtek AC’97 CD-ROM drive. System during installation, the default installation of the latter, there is the text of the fault. It appears on the taskbar a small speaker icon does not necessarily represent the sound card drivers installed correctly
